Quantum Computing

ZKSF, the Zero Kelvin Simulation Foundry, puts quantum computing in your pocket: certified quantum simulation and real quantum hardware, on demand, with no specialized infrastructure and no institutional access required.

Write a quantum circuit in OpenQASM, pick a ready-made one, or let the router choose an engine for you. Every result comes back with a documented accuracy statement, because an approximate answer without an error bar is an assertion, not a measurement.

REAL QUANTUM PROCESSORS

Eight QPUs from seven manufacturers across all four hardware technologies, billed at the provider's own rate with no markup:

• Rigetti Cepheus-1, 108 superconducting qubits

• IQM Emerald, 54 superconducting qubits

• IQM Garnet, 20 superconducting qubits

• IonQ Forte Enterprise 1, 36 trapped-ion qubits

• AQT IBEX Q1, 12 trapped-ion qubits

• QuEra Aquila, 256 neutral atoms

• Pasqal FRESNEL, 100 neutral atoms

• Quandela Belenos, 12 photonic qubits over 24 optical modes

The same OpenQASM circuit runs on any of the five gate machines. Neutral-atom hardware takes a pulse sequence and photonic hardware takes a linear-optics circuit, so those are offered ready to run. Every engine shows its rate before you choose it, and shot counts are held inside what each device actually accepts.

SEVENTEEN ENGINES, ONE APP

Exact statevector simulation to 30 qubits on CPU and 32 on GPU. Stabilizer simulation of Clifford circuits at 5,000 qubits, returned in under a second. Tensor-network matrix product state simulation to around 128 qubits, with certified error bounds. Pauli propagation for expectation values past 100 qubits. Device-noise preview with zero-noise error mitigation. Exact neutral-atom analog dynamics and exact photonic linear optics.

TEN READY-MADE PROGRAMS

Tap and run, no typing required:

• GHZ / Bell state, quantum entanglement

• Grover search

• QAOA MaxCut, combinatorial optimization

• VQE, H2 molecule ground state

• Bernstein-Vazirani

• Quantum teleportation

• Rydberg blockade, three atoms

• Antiferromagnetic chain, seven atoms

• Hong-Ou-Mandel, exact photonic simulator

• Hong-Ou-Mandel, on Quandela Belenos hardware

CERTIFIED RESULTS

ZCC-v0.1 certifies simulation accuracy: a fast convergence check by default, and an opt-in measured bound for results you need to defend. ZHF-v0.1 certifies quantum hardware fidelity by comparing measured counts against the exact ideal distribution. Every finished job exports a public certificate that anyone can check with our open-source verifier, without an account and without going through us.

COST AND CONTROL

Circuits get a free cost and feasibility estimate before you commit a penny. Circuits that would return an inconclusive answer are rejected with a diagnostic saying exactly why and what would work instead. Track your credit, your spend by tier and your payment history in the app, and manage or delete your account from your phone. Pure pay-per-use: no subscription, no minimum spend.
